Stephen Foster's entree into the world of horse racing was through his older brother Morrison ("Mit") who owned & raced a few ponies when he worked at Cadwaller's Mills in Pittsburgh, PA.

Mit stabled his horses at Massingham's Stable, Ferry & Water Sts., Pittsburgh where future minstrel Dan Rice was a stable boy and jockey. Rice was a frequent guest baritone at the Cadwaller & Foster homes.

Pittsburgh's camptown at the time was across the river in Allegheny City, present day location of Exposition Park III.

Would have made a fairly lasting impression on a teenage Stephen Foster.
